you are a tiny minority and a specialized browser fork is a great solution for your use case in this situation.
I just worry that people using some of these alternative browsers are opening themselves up to security issues since those code bases are less well-tested for security problems, and often they don't have the developer resources to implement things like process isolation and sandboxing.
Absolutely. The web browser is one of the most notorious attack vectors on computers these days. I find it hilarious that a vocal minority of power users is protesting this _massively impressive_ Firefox release just because they lost Tree Style Tabs or some extensions for downloading videos. Switching to a legacy fork like Waterfox or Firefox 52 ESR is not an enlightened move!
